This hardware configuration provides four independent fail-safe channels to actuate field-level final control elements, including safety valves, solenoids, and indicators. By incorporating strict dual-channel internal processing, this module drives safety-critical loops in emergency shutdown (ESD), fire and gas (F\u0026amp;G), and high-availability process control setups.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eManufacturer: HIMA Paul Hildebrandt GmbH + Co KG\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePart Number: F3334\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eProduct Category: PLC Digital Output Module\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSafety Certification Level: IEC 61508 SIL3 \/ IEC 61511\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eChannel Count: 4 independent fail-safe output channels\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eNominal Supply Voltage: 24 VDC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRated Switching Current: 2.0 Amperes per channel\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMaximum Power Consumption: 5.0 Watts\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMaximum Internal Voltage Drop: 2.0 V at 2.0 Ampere full load\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAdmissible Maximum Line Resistance: 3.6 Ohms\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eUndervoltage Trip Threshold: Less than or equal to 16.0 VDC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMaximum Channel Leakage Current: 550 Microamperes\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSpace Requirement: 4 TE backplane width slot\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePhysical Dimensions: 2.1 cm x 19.0 cm x 12.8 cm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eNet Component Weight: 0.24 KG\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCountry of Origin: Germany\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHardware Condition: 100% Brand New Original Stock\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eEngineering Advantages\u003c\/h3\u003e\n\u003ch3\u003eComprehensive Fault Isolation and Self-Diagnostics\u003c\/h3\u003e\n\u003cp\u003eThe internal architecture continuously traces line integrity, monitoring each output path for short circuits, line breaks, and undervoltage faults. When the module identifies an abnormal state or drops below the 16 VDC threshold, it trips the affected channel cleanly while maintaining operation across the remaining loops. This localized fault containment isolates field failures before they corrupt the central processing bus.\u003c\/p\u003e\n\u003ch3\u003eInductive and Resistive Heavy-Duty Actuation\u003c\/h3\u003e\n\u003cp\u003eEach of the four outputs switches up to 2.0 Amperes without requiring interposing relays. The robust internal solid-state design absorbs high inductive kickback from large solenoid valves and emergency trip relays. This direct-drive capability simplifies marshaling cabinet wiring, minimizes total component count, and eliminates mechanical contact wear.\u003c\/p\u003e\n\u003ch3\u003eThermal Resilience in Packed Marshaling Enclosures\u003c\/h3\u003e\n\u003cp\u003eThe compact 4 TE form factor optimizes chassis space, allowing system builders to group multiple output zones together. The efficient 5-Watt power distribution minimizes heat dissipation during continuous full-load deployment. This low thermal profile protects nearby components from heat aging and eliminates the need for active climate control within typical -20 to +60 degrees Celsius operational footprints.\u003c\/p\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eDoes this module require an external freewheeling diode for inductive loads? No. The F3334 integrates internal surge protection that suppresses inductive voltage spikes when driving solenoids or magnetic contactors. Engineers can wire standard inductive loads directly to the output terminals without external suppressing components.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow does the module handle a control line break scenario? The embedded diagnostics send a tiny supervisory current through the loop during the off-state. If a field wire snaps, the module detects the drop in leakage current, logs a line break fault in the central safety system log, and illuminates the corresponding front panel diagnostic LED.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan I parallel multiple channels on the F3334 to handle loads higher than 2 Amperes? No. Paralleling channels to increase current capacity violates the SIL3 safety compliance parameters. You must limit the continuous load of each discrete loop to a maximum of 2.0 Amperes to prevent thermal overload and preserve fail-safe switching execution.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HIMA","offers":[{"title":"Default Title","offer_id":43394475917402,"sku":"F3334","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/215._5bc10683-f1d5-4c1d-b8f3-3fa2c479928e.jpg?v=1779244592","url":"https:\/\/www.spareoil.com\/products\/hima-f-3334-brand-new-24vdc-2a-safety-output-unit","provider":"SpareOil Automation","version":"1.0","type":"link"}
